 [patch 01/16] use libnuma api to create memory on a specified node
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

With latest Linux kernel, the memory pages gets migrated from the original node to
the one where it's now being accessed, then the RMA is changed to LMA.

This patch uses libnuma API to tell kernel it doesn't need to migrate the memory pages.

 [patch 02/16] add cache monitoring and memory bandwidth monitoring
 features
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

The feature is only supported on Intel Xeon V4 family.

Note that this feature requires kernel CQM/MBM patch but the patch
has not been upstreamed yet (target for 4.7). So please apply following
kernel patch before using numatop cache monitoring and memory bandwidth
monitoring features.

 [patch 05/16] common/os: fix null pointer dereference on nrec
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

pf_profiling_record checks that nrec is NULL, however, a subsequent call
from this function to profiling_recbuf_update dereferences nrec by a read
and a write.  Fix this by checking if nrec is NULL and returning early
in profiling_recbuf_update to avoid the dereference bug.

Fixes warning from clang scan-build:

common/os/pfwrapper.c:380:6: warning: Dereference of null pointer (loaded from variable 'nrec')
        i = *nrec;

 [patch 06/16] do not print garbage latency if lat_data_get fails to
 get latency
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

It is possible for lat_data_get to not succeed in reading the latency,
in which case the latency contains a garbage value and this misleading
value is printed.  Instead, print "unknown" if we cannot fetch the latency
to indicate that it could not be read rather than emiting an incorrect
garbage value.

 [patch 07/16] initialise nprocs to zero to avoid printing garbage
 nprocs value

Content-Transfer-Encoding: 8bit

nprocs is not intialized, so we can call reg_scroll_show passing a
garbage value of nprocs from the stack.  Instead, initialize it to
zero so we don't have a random garbage value being emitted.

Fixes clang scan-build warning:

common/win.c:3403:2: warning: Function call argument is an uninitialized value
